Abstract

Tumor markers are grouped into diagnostic and prognostic markers. Specific diagnostic markers appear extensively in cells of a particular neoplasm and not in other tumors. These markers can be used to assess the cellular lineage and histogenic origin of various neoplasms. Thus, diagnostic markers can be used for the confirmatory diagnosis of various tumors. This paper reviews the literature on various diagnostic markers and aims to group them based on the cellular lineage of neoplasms.
